STAGE 1 PRELIMINARY SITE INVESTIGATION

NEW ENGLAND HIGHWAY UPGRADE –

BELFORD TO GOLDEN HIGHWAY

ENVIRONMENTAL EARTH SCIENCES NSW PREPARED FOR ARUP PTY LTD 21 FEBRUARY 2017

115085_V7

EXECUTIVE SUMMARY Environmental Earth Sciences was commissioned by Arup Pty Ltd (Arup) to undertake this Stage 1 Preliminary Site Investigation (PSI) for the areas involved in the proposed upgrade of the Golden Highway and New England Highway, Belford, NSW. This report has been prepared to support the overarching Review of Environmental Factors (REF) study commissioned by Roads and Maritime. The study area incorporated current lots and road easements both within and adjacent to the project area. A historical report identified one lot within the project area where suspect cattle tick dipping may have occurred and a timber treatment yard was suspected to have been located. Based upon findings of the inspection no evidence of commercial / industrial land use within the project area was identified. Potential contamination from the suspected cattle tick dip and timber treatment yard was not observed. The inspection identified the following land uses outside of the project area whereby commercial activity or development has taken place, however no indications or observations of contamination relating to these adjacent lots were noted to impact the project area:

Lot 21 in DP1014307 – retail service station operating underground petroleum storage system (UPSS);

Lot 35 in DP1128981 – abattoir operation with associated cattle pens and water treatment / irrigations paddocks. The main works area is situated far south of the proposed works corridor; and

Lot 24 in DP1128978 – now vacant property that was used as a construction compound during the Great Northern Railway line bridge over the Golden Highway upgrade circa 2009.

During the site inspection indications of surface salt scalding consistent with dryland salinity were noted within the project area (along the northern margin of Lot 35 in DP1128981). Although not an indicator of contamination, potential saline conditions could potentially degrade concrete used in construction. Potential salinity issues are recommended to be investigated across a range of landscapes over the site with assessment undertaken with reference to should be planned with reference to the Department of Land and Water Conservation (2002) – Site Investigations for Urban Salinity (DLWC, 2002). Prior to commencement of proposed construction works it is recommended that a Construction Environmental Management Plan (CEMP) be prepared to include (but not limit) procedures for controls / management of:

soil erosion, sedimentation and dust generation;

soil / spoil stockpile management including onsite / off-site material tracking and beneficial reuse / waste disposal options;

general erosion, sediment and water quality control safeguards (e.g. sediment basins, stockpile areas, wash-downs, batch plants, refuelling and chemical storage sites) involving lining and/or bunding if they are located within 50 m of a shallow groundwater source);

115085_V7

rehabilitation of works area;

dewatering management;

spill response and associated emergency planning;

personal protective equipment (PPE) controls for construction workers;

Unexpected Findings Protocol (UFP) procedure for managing instances where gross contamination and/or hazardous materials are encountered, with appropriate consideration of WH&S controls for mitigating risk to construction workers.

1 INTRODUCTION & BACKGROUND Roads and Maritime Services (Roads and Maritime) propose to upgrade the New England Highway between Belford and the Golden Highway. The road upgrade would improve traffic flow, travel times and safety for motorists along a busy section of the New England Highway. The proposal would provide a divided road with two travel lanes in each direction between Belford and the Golden Highway and a flyover for vehicles turning right from the Golden Highway towards Maitland and Newcastle. The project is located within the Singleton local government area (LGA) and the Hunter region of the Roads and Maritime network. Key features of the project include:

Widening the New England Highway for around 3.2 km to provide a divided road with two travel lanes in each direction between Belford and the Golden Highway

Replacing the existing right turn movement from the Golden Highway to the New England Highway with a right turn flyover

Removal of the Whittingham rest area adjacent to the New England Highway and Golden Highway intersection.

Environmental Earth Sciences was commissioned by Arup Pty Ltd (Arup) to undertake this Stage 1 Preliminary Site Investigation (PSI) for the corridor of the abovementioned project near Belford, NSW (the “project area”). The assessment also reports on potential contamination in lots adjacent to the project area that have been historically developed or currently used for commercial purposes (the “study area”). Refer to Figure 1 for location of the project area. A preliminary environmental investigation report prepared by Hills Environmental Pty Ltd (2014) - SH9 New England Highway Upgrade - Belford Deviation to SH27 Golden Highway Junction Preliminary Environmental Investigation (ref: RPT-PEI-J000134-2014-06-V 02.docx; dated 19 June 2014) (the “PEI”) identified the following current and historical potentially contaminating land uses:

Onsite former timber treatment post yard.

Onsite former rail cattle yard on the northern side of the New England Highway about 350 metres east of the Golden Highway intersection.

Offsite retail service station situated on the western side of the New England Highway. Inspection of historical aerial images reported other potentially offsite features such as a former building compound and an abattoir which could pose a potential offsite risk to works within the works corridor.

2 OBJECTIVE With reference to requirements of the NSW Office of Environment and Heritage (OEH) (2011) – Contaminated Sites: Guidelines for Consultants Reporting of Contaminated Sites (OEH, 2011) this report aims to:

review site history and other available information to identify potential sources and areas on site affected by current and historical contamination;

identify potentially affected media (soil and groundwater);

determine potential contaminants of concern; and

identify potential human and ecological receptors and complete exposure pathways that could pose an unacceptable risk to future users of the site and the environment.

The Stage 1 PSI will ascertain if current / historical activities in the study area (west) have resulted in contamination which may require appropriate Stage 2 detailed assessment to further delineate and characterise risk and/or require management to ensure that the contamination in the corridor does not present unacceptable risk to users of the site and the environment.

3 WORKS UNDERTAKEN Works undertaken for this Stage 1 PSI included:

review of the PEI report;

inspection of the study area undertaken on 21 January 2016 to ascertain land-use features and assess locations of potential contamination identified in the PEI report;

general desktop assessment including the obtaining information from the following sources:

o geology, soil, acid sulfate soils, hydrology and meteorology maps and databases (undertaken 17 January 2016);

o Section 149 (1) and (5) council planning certificate for a service station property adjacent to the project area (undertaken 30 October 2015);

o SafeWork NSW dangerous goods information for service station property adjacent to the project area (undertaken 11 February 2016);

o historic aerial photography;

NSW Environment Protection Authority (EPA) search of register of notified properties under the Contaminated Land Management act 1997 (CLM Act) subject to investigation / remediation orders (search undertaken on 17 January 2016);

preparation of this Stage 1 PSI report to detail findings.

4 SITE CONDITION AND SURROUNDING ENVIRONMENT

4.1 Site Identification The site is a combination of entire lots and portions of lots within a mainly rural area approximately 40 kilometres south of Singleton. The ‘study area’ for this assessment encompasses an area slightly larger than the ‘project area’ and constitutes the boundary for this Stage 1 PSI. Most lots within the project area have only historically been used for rural / agricultural purposes, or developed for highway corridors. A summary of the site details are presented in Table 1.

4.3 Sensitive receptors

The following potential receptors have been identified for the site:

onsite human –

o residents, visitors and employees of rural properties;

o construction workers during proposed upgrade works; and

o maintenance workers (roads and utilities);

offsite human –

o residents, visitors and employees of rural properties and service station site;

o recreational users of the Hunter River and Jumpup Creek;

onsite ecological –

o surface water (two unnamed creeks to the east of the service station);

o groundwater (freshwater environment);

115085_V7 7

offsite ecological –

o surface water (Mudie’s Creek to the west; Jumpup Creek to the east; Hunter River to the north).,

o groundwater (freshwater environment).

4.5 Regional Geology

A search of the Rasmus et al (1969) Singleton 1:250,000 Geological series sheet S1/56-01 undertaken on 17 January 2016 reported that the site is directly underlain by the Permian-aged Mulbring Siltstone Formation of the Maitland Group, consisting of siltstones and sandstone.

4.6 Regional Soil A search of the Kovac and Lawrie (1991) - Soil landscapes of the Singleton 1:250,000 sheet undertaken on 17 January 2016 reported that regional soils belong in the ‘Rothbury’ landscape. Soils typical of this landform are noted to consist of the following characteristics:

red podzolic soils (Dr3.21, Dr5.21) on upper slopes;

yellow Podzolic soils (Dy2.41) on mid slopes;

yellow solodic soils (Dy.42) and Brown Soloths (Db3.40) on lower slopes; and

prairie soils (Gn4.22) in the drainage lines.

4.7 Topography and drainage The site is situated from approximately 86 metres above Australia Height Datum (mAHD) just west of the picnic area, to approximately 62 mAHD in a drainage depression just south of the highway junction. Landscapes in this area generally consist of undulating to rolling hills with elevations ranging from 60 – 140 metres. Average slopes are 6 – 10% with some slopes up to 12%. Slope lengths are 800 – 1,000 metres with local relief of 60 – 80 metres. Drainage lines are common throughout the area and occur at intervals between 200 – 1,000 metres (Kovac and Lawrie, 1991). At the time of inspection on 21 January 2016 the majority of the existing rural properties comprising the study area were unsealed. As such there would be a high degree of infiltration and recharge to groundwater. Sealed areas within the study area comprise the tarmac sections of the highway corridor, where precipitation would run-off onto adjacent off-seal areas, or be redirected into engineered stormwater infrastructure.

4.8 Acid Sulfate Soils A search of the Singleton LEP (2013) undertaken on 17 January 2016 reported that the site does not lie in an area requiring management for potential inland acid sulfate soils (PASS).

Th is w as conf irm ed t h rough t he Department of Land and Water Conservation acid sulfate soil risk map for Singleton (Naylor, 1995) which indicated a low likelihood for PASS occurrence in the vicinity of the site.

115085_V7 8

4.9 Salinity A search of the online NSW Soil and Land Information System (eSPADE) undertaken on 17 January 2016 indicated that three exploratory test pit excavations have been advanced in the vicinity of the site at the Belford-Singleton Abattoir site. Of the three pits two were reported with no salting evident, and one indicating that salting was strongly evident. Refer to the individual eSPADE soil profile reports and associated locality map in Appendix A.

115085_V7 9

4.10 Hydrogeology A search of the NSW Office of Water “waterinfo.nsw” website undertaken on 17 January 2016 identified four registered groundwater bores located at the service station adjacent to the study area (Lot 21 in DP1014307). All bores were used for monitoring purposes with details search results and a map of bore locations included in Appendix B. A summary of bore information is included in Table 3.

The majority of the study area is rural with the exception of the service station (Lot 21 in DP1014307), and the abattoir.

Associated with the abattoir (Lot 35 in DP1128981), large expanses are seemingly utilised for irrigation with treatment water, as paddocks to the south of the New England Highway appear quite fertile;

Property Lot 24 in DP1128978 appears to have miscellaneous tipping evident. It also appears to have been cleared in places;

The wider area appears to be predominantly rural-residential with the exception of the following features:

- small township of Belford approximately 5km east.

- Dochra Airfield approximately 2km west.

- Singleton Military Area approximately 7km southwest.

- Walkworth coal mine approximately 12km west.

5.2 Council Planning Certificate The Council planning certificates issued under Section 149 [2] & [5] of the NSW Environmental Planning and Assessment Act 1979 (EP&A Act) were obtained for the service station property (Lot 21 in DP 1014307 - issued 30 October 2015) situated adjacent to the project area. These certificates state:

Lot not significantly contaminated within the meaning of that CLM Act at the date when the certificate was issued;

Lot not subject to a management order within the meaning of the CLM Act at the date when the certificate was issued;

Lot not the subject of an approved voluntary management proposal (VMP) with the meaning of that CLM Act when the certificate was issued;

Lot not the subject of an ongoing maintenance order within the meaning of that CLM Act when the certificate was issued; and

Lot not subject to a site audit statement within the meaning of the CLM Act if a copy of such a statement has been provided at any time to the local authority issuing the certificate.

The Section 149 (2) and (5) certificate is included for reference in Appendix C.

5.3 SafeWork NSW Dangerous Goods Search A search of hazardous chemical storage records held by SafeWork NSW was undertaken for the offsite service station property (Lot 1 in DP1014307). This property currently has records pertaining to licence 35/035078. Earliest available records pertain to design drawings for seven underground depots and one above-ground depot dated 1997 and approved on 14 June 2000. It would appear that the eight underground storage tanks originally constructed circa 2000 are still in commission, and that there have been no alterations or equipment replacement. At the time of the site inspection this service station offsite was operational. Details of product licensing and dates of associated storage information provided are not exhaustive or complete, and information returned from by NSW WorkCover represents available information only. Returned information is summarised in Table 6 and included in Appendix D.

5.4 NSW EPA Contaminated Sites Register A search of the NSW EPA contaminated land public record database showed no notices or records for the lots within the study area. There is no record for any lots within the study area having ever been included on the following list of NSW EPA notices issued in accordance with CLM Act:

declaration of an investigation area (under Section 15 of the CLM Act);

declaration of a remediation site (under Section 21 of the CLM Act);

investigation order (under Section 17 of the CLM Act);

remediation order (under Section 23 of the CLM Act);

voluntary investigation proposal (under Section 19 of the CLM Act);

voluntary remediation proposal (under Section 26 of the CLM Act); and

site audit statement (SAS) with (under Section 53B of the CLM Act).

115085_V7 14

5.5 Review of historical report pertaining to site The only environmental report available for review was the PEI report. This report identified the following current and historical potentially contaminating land uses within the site:

former timber treatment post and cattle rail yard (Lot 4 in DP621020) located on the northern side of the New England Highway; and

service station situated outside of the project area on the western side of the New England Highway (Lot 21 in DP1014307).

The report noted that facilities such as a cattle rail yard usually contained cattle dip or spray infrastructure which used organochlorine pesticides to treat parasites, with these facilities used in Australia up until the early 1960’s. Arsenic was also noted in the PEI report to have been used in sheep dips in Australia up until the late 1980’s (Meat and Livestock Australia, 2014) although no remaining physical evidence of this infrastructure was observed during the site inspection. A potential for residual organochlorine pesticide and arsenic contamination was identified as possibly existing in Lot 4 in DP 6121020 in the PEI report. The PEI report noted that a search of acid sulfate soil risk map (Naylor, 1995) was undertaken, which did not identify risk of acid sulfate soils at any level within their subject study area.

6 SITE OBSERVATIONS & POTENTIAL FOR CONTAMINATION

A site walkover was undertaken by Environmental Earth Sciences on 21 January 2016. Access was granted and walkover undertaken upon the following works corridor areas and adjacent lots:

Lot 24 in DP1128978 (former works compound);

Lot 23 in DP1128978;

Lot 4 in DP621020 (cattle yard);

Lot 35 in DP1128981 (abattoir land); and

Lot 34 in DP1128981;

Rest stop / picnic area. Limited inspection of the following lots was able to be undertaken from the road corridor:

7 CONCEPTUAL SITE MODEL A conceptual site model (CSM) of the site can be formed by considering the likelihood of pathways between any source(s) of contamination onsite and potential receptors. An initial CSM for the project area had been undertaken for in the PEI report, which identified certain lots within the project area suspected to be potentially contaminated from historical activities. Re-evaluation of the CSM in this assessment was undertaken through review of available desktop information and site inspection A summary on the source-pathway-receptor evaluation is provided in Table 8.

Notes: 1. HIGH RISK - desktop review and site inspection have identified potentially contaminating site activities and intrusive works must be carried out to confirm the presence or absence of

contamination

2. MODERATE RISK - desktop review and site inspection cannot rule out the presence of potentially contaminating site activities without undertaking recommended intrusive works MODERATE 1 - potential for contamination is limited in either likelihood or extent and the presence or absence of contamination is expected to be resolved by limited targeted sampling MODERATE 2 - potential for contamination is greater or more extensive than Moderate 1 and will require a detailed site investigation to confirm the presence or absence of contamination

3. LOW RISK - desktop review and site inspection have not identified any potentially contaminating site activities

8 CONCLUSION Roads and Maritime Services (Roads and Maritime) propose to upgrade the New England Highway between Belford and the Golden Highway. The road upgrade would improve traffic flow, travel times and safety for motorists along a busy section of the New England Highway. The proposal would provide a divided road with two travel lanes in each direction between Belford and the Golden Highway and a flyover for vehicles turning right from the Golden Highway towards Maitland and Newcastle. The project is located within the Singleton local government area (LGA) and the Hunter region of the Roads and Maritime network. Key features of the project include:

Widening the New England Highway for around 3.2 km to provide a divided road with two travel lanes in each direction between Belford and the Golden Highway

Replacing the existing right turn movement from the Golden Highway to the New England Highway with a right turn flyover

Removal of the Whittingham rest area adjacent to the New England Highway and Golden Highway intersection.

Environmental Earth Sciences was commissioned by Arup to undertake this Stage 1 PSI for the above-mentioned works. Works included a review of the PEI report, obtaining relevant desktop information on site setting, and undertaking an inspection of the following two locations reported in the PEI as being potential sources of contamination:

cattle holding pen and possible tick dip within the project area (Lot 4 in DP621020); and

service station adjacent to project area (Lot 21 in DP1014307). The inspection was undertaken by Environmental Earth Sciences on 21 January 2016 and noted the study area to consist of various rural lots and highway corridors. During the inspection the following offsite land uses adjacent to the project area were also noted as posing potential sources of contamination:

former works compound (Lot 24 in DP1128978) adjacent to project area that was involved in the upgrade of the Golden Highway vehicular bridge over the Great Northern Railway line between 2009 – 2013; and

operational abattoir and process water treatment/irrigation area to the south of the project area (Lot 35 in DP1128981).

Based on the findings of the desktop assessment and site inspection, the CSM for potential contamination risk was re-evaluated. In summary:

No potential sources of contamination or observations of contamination impact were noted in the project area which would pose unacceptable risk to human health or the environment. Hence an overall low risk posed by contamination;

Potential risks posed from current operation of the abattoir /irrigation paddocks adjacent to the project area were evaluated as posing a low risk;

Potential risk posed by operation of the service station adjacent to the project area were evaluated as posing a low risk pending that operations comply with the UPSS regulations;

115085_V7 21

Potential risks posed from residual contamination in the former bridge construction works compound adjacent to the project area were evaluated as posing a low risk;

Based on the above no further Stage 2 Detailed Site Investigation is recommended to be undertaken in the project area. General management recommendations are provided in Section 9.

9 RECOMMENDATIONS

9.1 General construction management Prior to commencement of proposed construction works it is recommended that a Soil Management Plan (SMP) be prepared in accordance with QA Specification G38 and implemented as part of any overarching Construction Environmental Management Plan (CEMP). This plan should include (but not limit) procedures for:

Identification of all reasonably foreseeable risks relating to subsurface impacts and pollution associated with construction of the proposal and description on how these risks would be managed and minimised.

Stockpile generation and management in accordance with RTA Stockpile Site Management Guideline. Batters would be designed and constructed to minimise risk or exposure, instability and erosion, and to support long-term, on-going best practice management, in accordance with the Roads and Maritime Guideline for Batter Stabilisation Using Vegetation.

Environmental controls during earthworks, including management / controls for erosion, sedimentation, dust generation and water quality safeguards.

Identification of, and associated procedures / controls for lining / bunding the following areas located within 50 m of a shallow groundwater source:

o Sediment basins.

o Stockpiles.

o Wash-downs.

o Batch plants;

o Refuelling sites; and

o Chemical storage sites;

Managing pollution risks associated with spillage or soil contamination on the site and adjoining areas, and monitoring during and post-construction;

Onsite / off-site soil material tracking of soil / spoil.

Appropriate classification of soil / spoil that requires disposal to waste facility. This is to be undertaken in accordance with the NSW EPA (2014) – Waste Classification Guidelines.

Appropriate certification of Virgin Excavated Natural Material (VENM) or Excavated Natural Material in accordance with the NSW Protection of the Environment Operations Act 1997 (POEO Act).

General PPE controls for construction workers;

115085_V7 22

Consistent with any specific requirements of an approved Erosion and Sedimentation Control Plan (ESCP) and the SMP, control measures should be implemented to minimise risks associated with erosion and sedimentation and entry of materials into the creek / drainage lines. This may include, but not necessarily be limited to:

o Sediment management devices, such as sediment fencing, straw bales or sand bags;

o Installation of measures at work entry and exit points to minimise movement of material onto adjoining roads, such as rumble grids or wheel wash bays

o Appropriate location and storage of construction materials, fuels and chemicals, including bunding where appropriate.

Unexpected Findings Protocol (UFP) procedure for managing instances where gross contamination and/or hazardous materials are encountered, with appropriate consideration of WH&S controls for mitigating risk to construction workers.

Pre-construction preliminary salinity field investigation is to be considered with locations, profile descriptions, soil tests and laboratory analyses planned with reference to the Department of Land and Water Conservation (2002) – Site Investigations for Urban Salinity (DLWC, 2002).

Rehabilitation of disturbed areas would be carried out progressively as construction stages are completed, and in accordance with:

o Landcom's Managing Urban Stormwater: Soils and Construction series;

o RTA Landscape Guideline;

o Roads and Maritime Guideline for Batter Stabilisation Using Vegetation.

9.2 Spoil and fill management A Spoil and Fill Management Plan (SFMP) is to be prepared and implemented as part of any overarching CEMP. The SFMP should identify:

Locations of any spoil / stockpiles;

Sources of imported fill, and methods to re-use or dispose of excess or unsuitable spoil material including estimated volumes and disposal sites

9.3 Specific contamination mitigation measures If contaminated areas are encountered during construction, appropriate control measures are to be implemented to manage the immediate risks of contamination, such as:

Diversion of surface runoff;

Capture of any contaminated runoff; or

Temporary capping. All other work that may impact on the contaminated area should cease until the nature of the contamination has been confirmed and any necessary site-specific controls or further actions are identified in consultation with the Environment Manager and/or EPA.

115085_V7 23

9.4 Spill management A site specific emergency spill plan is to be developed and implemented. The plan should be prepared in accordance with the Roads and Maritime Code of Practice for Water Management and/or relevant EPA guidelines. The plan should include measures to be implemented in the event of a spill, including:

initial response and containment;

notification of emergency services and relevant authorities (including Roads and Maritime and EPA officers).

Procedures for managing pollution risks associated with spillage or soil contamination on the site and adjoining areas.

9.5 Dewatering management Where groundwater is intercepted during construction works, such as around the flyover, management measures to minimise potential adverse impacts are to be implemented in accordance with the RTA Technical Guideline: Environmental management of construction site dewatering. These may include, but not necessarily be limited to:

Options to collect and store groundwater to enable recharge of the water table (such as via grassed swales);

Where recharge is not appropriate or feasible, discharging groundwater to the surface water drainage system following;

Appropriate treatment to ensure discharged water is of sufficient quality;

Prior to any dewatering activities being carried out, an approval must first be obtained in accordance with Section 92 of the Water Management Act.

ENVIRONMENTAL EARTH SCIENCES GENERAL LIMITATIONS Scope of services The work presented in this report is Environmental Earth Sciences response to the specific scope of works requested by, planned with and approved by the client. It cannot be relied on by any other third party for any purpose except with our prior written consent. Client may distribute this report to other parties and in doing so warrants that the report is suitable for the purpose it was intended for. However, any party wishing to rely on this report should contact us to determine the suitability of this report for their specific purpose.

Separation of information and data This formal report in its entirety will be appended within the overarching REF and will comprise the report body, tables, figures and appendices as referred to in the index of this report. It may be summarised only within the overarching REF document prepared for Roads and Maritime, but the appended report must not be copied in part without all the material included for any reason.

Subsurface conditions change Understanding an environmental study will reduce exposure to the risk of the presence of contaminated soil and or groundwater. However, contaminants may be present in areas that were not investigated, or may migrate to other areas. Analysis cannot cover every type of contaminant that could possibly be present. When combined with field observations, field measurements and professional judgement, this approach increases the probability of identifying contaminated soil and or groundwater. Under no circumstances can it be considered that these findings represent the actual condition of the site at all points. Environmental studies identify actual sub-surface conditions only at those points where samples are taken, when they are taken. Actual conditions between sampling locations differ from those inferred because no professional, no matter how qualified, and no sub-surface exploration program, no matter how comprehensive, can reveal what is hidden below the ground surface. The actual interface between materials may be far more gradual or abrupt than an assessment indicates. Actual conditions in areas not sampled may differ from that predicted. Nothing can be done to prevent the unanticipated. However, steps can be taken to help minimize the impact. For this reason, site owners should retain our services.

Problems with interpretation by others Advice and interpretation is provided on the basis that subsequent work will be undertaken by Environmental Earth Sciences NSW. This will identify variances, maintain consistency in how data is interpreted, conduct additional tests that may be necessary and recommend solutions to problems encountered on site. Other parties may misinterpret our work and we cannot be responsible for how the information in this report is used. If further data is collected or comes to light we reserve the right to alter their conclusions.

Obtain regulatory approval The investigation and remediation of contaminated sites is a field in which legislation and interpretation of legislation is changing rapidly. Our interpretation of the investigation findings should not be taken to be that of any other party. When approval from a statutory authority is required for a project, that approval should be directly sought by the client.

Limit of liability This study has been carried out to a particular scope of works at a specified site and should not be used for any other purpose. This report is provided on the condition that Environmental Earth Sciences NSW disclaims all liability to any person or entity other than the client in respect of anything done or omitted to be done and of the consequence of anything done or omitted to be done by any such person in reliance, whether in whole or in part, on the contents of this report. Furthermore, Environmental Earth Sciences NSW disclaims all liability in respect of anything done or omitted to be done and of the consequence of anything done or omitted to be done by the client, or any such person in reliance, whether in whole or any part of the contents of this report of all matters not stated in the brief outlined in Environmental Earth Sciences NSW’s proposal number and according to Environmental Earth Sciences general terms and conditions and special terms and conditions for contaminated sites. To the maximum extent permitted by law, we exclude all liability of whatever nature, whether in contract, tort or otherwise, for the acts, omissions or default, whether negligent or otherwise for any loss or damage whatsoever that may arise in any way in connection with the supply of services. Under circumstances where liability cannot be excluded, such liability is limited to the value of the purchased service.
